Changes
-------

Patch for branch-2.5 is attached to Apache JIRA


Bugs: AMBARI-21154
    https://issues.apache.org/jira/browse/AMBARI-21154


Repository: ambari


Description (updated)
-------

In a kerberized environment, Atlas hook uses JAAS configuration section named 
"KakfaClient" to authenticate with Kafka broker. In a typical Hive deployment 
this configuration section is set to use the keytab and principal of 
HiveServer2 process. The hook running in HiveCLI might fail to authenticate 
with Kafka if the user can't read the configured keytab.

Given that HiveCLI users would have performed kinit, the hook in HiveCLI should 
use the ticket-cache generated by kinit. When ticket cache is not available 
(for example in HiveServer2), the hook should use the configuration provided in 
KafkaClient JAAS section

As a solution need to add below in hive atlas-application.properties by default 
if atlas-hive hook is enabled in secure mode

atlas.jaas.ticketBased-KafkaClient.loginModuleControlFlag=required
atlas.jaas.ticketBased-KafkaClient.loginModuleName=com.sun.security.auth.module.Krb5LoginModule
atlas.jaas.ticketBased-KafkaClient.option.useTicketCache=true

The attached patch is for trunk branch, patch for branch-2.5 is attached to 
Apache Jira
